  • Chrysoteuchia curvicavus Song & Chen in Chen et al. 2001[1]: 186, figs 5, 11. Type locality: Wuyishan, Fujian Province, China. Type depository: Institute of Zoology, Chinese Academy of Sciences, Beijing.

Specimens examined

Description

Male adult (Figs 8, 9): Forewing length 9.5–11.0 mm. Frons and vertex white. Maxillary palpus pale brown, ending with white. Labial palpus pale brown. Antenna scapus white mixed with grey dorsally, pale brown ventrally; flagellomere pale brown and white alternately on dorsal surface, pale brown on ventral surface. Forewing ground colour white, costa densely covered with blackish brown scales between base and subterminal fasciae, the remaining suffused with sparse blackish brown scales along veins; median fascia blackish brown, angled outwards at anterior one fourth; two subterminal fasciae yellowish brown, out-curved at anterior one third; terminal area pale yellow; terminal fascia black, with three evenly spaced black spots; cilia shiny, pale brown, with greyish white basal line. Hindwing and cilia greyish white. Abdomen pale brown. Male genitalia (Fig. 10): Uncus apically curved downwards in lateral view, tapering to blunt apex. Gnathos basally broad, tapering to point tip, a bit shorter than uncus. Tegumen nearly four times as long as gnathos, with narrow dorsal bridge. Valva with sclerotised basal line near middle, apical quarter nearly triangular. Costa concave at approximately basal three-fifths. Sacculus narrow and thin, distal prong well-developed and reaching beyond apex of valva. Juxta heart-shaped, basely narrow, broadened towards tip, distal margin slightly concave. Phallus approximately half as long as valva, basal half broad, distal half narrowing towards tip and armed with two sclerotised wrinkles, apex pointed; cornutus absent.

Distribution

China (Sichuan, Fujian).

Remarks

The male of C.curvicavus is described for the first time. This species is similar to C.atrosignata (Zeller, 1877) in having an apical prong on the sacculus and a pointed apex on the phallus in the male genitalia. However, it can be easily distinguished by the distal prong of the sacculus reaching beyond the apex of the valva, and the phallus approximately half as long as the valva and armed with two sclerotised wrinkles (Fig. 10). In the latter species, the distal prong of the sacculus reaches beyond the costa at the basal three-fifths of the valva and the phallus is nearly as long as the valva and without sclerotised wrinkles (Bleszynski 1965[2]). The female of this species was described and figured adequately by Chen et al. (2001)[1].
